"We have cut crime across every single zone in the city of Atlanta by between 10 percent and 16 percent, depending on the zone," Reed announced.

Every zone? The Truth-O-Meter loves a good crime statistic, so we wound it up and let it whirl.

The Atlanta Police Department posts weekly crime data on its website. We clicked through it and found that while crime is down 11 percent across the city, it’s not down in all of the city’s six zones.

Ordinarily, we would check a claim like Reed’s by comparing the number of incidents in each zone for 2011 and 2009, the year before the mayor took office.

For this fact check, we took a slightly different approach. The department changed its zone boundaries on Dec. 13, 2011. If we used the standard method, a zone’s crime could appear to rise if its borders shifted to include a higher-crime neighborhood.

Instead, we looked at total incidents starting the first week of January 2011 to the week ending Dec. 10, 2011, the last full week before the switch. We compared it with the same time period in 2009.

We analyzed what the Federal Bureau of Investigation calls "Part I" offenses, or murders, rapes, robberies, aggravated assaults, burglaries, auto thefts, thefts from automobiles and larceny. Researchers think tallies of these crimes tend to be a good reflection of the actual number of incidents taking place.

Zone 6: Crime declined in these east Atlanta neighborhoods by 27 percent, led by a 45 percent drop in thefts from cars. Burglaries and aggravated assaults dropped by more than 30 percent.

Crime is down in Atlanta, but Reed mangled the specifics.

It’s down in all zones but one. And in the case of east Atlanta, where crime dropped 27 percent, the decline is far more dramatic than the 10 percent to 16 percent decrease Reed mentioned in his State of the City address.

In a written statement to PolitiFact Georgia, Reed acknowledged that the city has more work to do, but the lower overall crime rate is a sign of progress.

"One of our goals is to say with confidence that crime is down in all zones, and I believe we are moving in the right direction," Reed said.

Because Reed’s broader message held true, but the data he used are topsy-turvy, we grant him a Half True.
